Is the amount of sun your deck or fence receives each day limited? Our new and improved 4x4 White Fence Post Solar Cap Lights may be the answer to your sun problem! The circuitry and solar panels have been upgraded from 65m to 90m, which means that your solar post cap lights will charge faster and stronger than before. You no longer need 8 to 10 hours of sun on the solar panel during the summer, your solar fence cap lights will charge to full capacity in 6 hours in the summer. That is a problem solver!

You can choose the lighting and look of the post cap you want at your home. We have 8 different colors of LED bulbs, a Clear or Frosted lens, and a Painted Finish option to purchase. See below for all of your choices.

We also upgrade FOR FREE the Manufacturer's standard 400mah 3.2V battery to a 600mah 3.2V battery when you order, which will give you a bright light output for an additional 2 to 3 hours!

A Volume Discount of 10% to 20% will be automatically applied with a 3 Set Minimum Purchase of solar fence post lights.

These low profile, low maintenance, green product solar post cap lights are also available in a Black and a Copper finish with the same choice of LED colors. Choices that will match any outdoor style you want. You will receive Free Shipping on any color.

Mounting Base Options to choose from for your order are a 3.75" x 3.75" base, which fits nominal wood 4x4 posts which actually measure 3.5", and a 4 1/16 " x 4 1/16" base, which will fit true 4x4 Vinyl/PVC posts.

    These lights emit the perfect amount and quality of warm light that's almost impossible to find in other solar light products. They fit snugly over a 4x4 trex post wrap. Nice quality housing and easy access to battery. The only thing I would have done differently is pay a little extra for the shinier housing for a more perfect match with the existing caps....standard housing has matte finish. But, the difference is only visible up close. A great product with many options to choose from. Would definitely recommend!

    The ability to customize these lights to exactly what we wanted was great! Installation was a breeze. We've had them for about a week now, and they've been working perfectly. They're still lit even when I get up in the morning.

    I would absolutely recommend these lights, and definitely recommend this company, as well.

    I found these nice looking lights on line but, I had some questions so I called to get more info. Talked with a very helpful/knowledgeable lady who answered all my questions and took my order. Painless! Received them undamaged in the time frame promised. Easy to install and they exceeded my expectations. I would do business with this company again.
